Part Number: AM3358
Other Parts Discussed in Thread: AM3352, TPS65910

hello,

we have dev. an am3358 based custom board with ref. design of sitara kit

there is only one change in our board there is two ddr3 ram and we have configure board.c for the same

at boot time we are getting log such as

U-Boot SPL 2019.01-g1ebdbc7d8b-dirty (Jan 29 2020 - 18:41:33 +0530)

Hi Raju,

RAJU KUMARKHANIYA said:

there could be a number of things going wrong here including but not limited to DDR config including how this information is passed to the Kernel, the Kernel using some improper/unsuitable build configuration, issues with the device tree file, issues with how the Kernel boot arguments are setup (UART), etc.

I would suggest using the JTAG debugger to do some analysis here for a quick path to resolution. A combination of JTAG and Code Composer Studio would also give you a platform to test and experiment with your DDR configuration which is often a reason why things don't work (I suppose you are aware of the the AM335x EMIF Tools App Note and its associated spreadsheet ?)

Alternatively, I suppose you have that Sitara development board you modeled your design after at your disposal? Make sure your Kernel/dtb runs there. Then try stripping it down to the bare minimum by de-activating different things in the Kernel configuration. Also try "hiding" some of your memory by experimenting with your DDR config to go back to the baseline you started from (512MB?) to see if this does anything. Do some "poor man's" basic mem testing by making sure all memory is readable and writable by using memory-manipulating commands such as 'md' and 'mw' and make sure all regions are accessible and the values "stick" by trying random locations across the entire range you expect to have memory (obviously this would be nothing more than a quick sanity test).

Then, you can try to enable early printk (console) functionality to see if this yields anything, configuring it for the UART you are using:

https://e2e.ti.com/support/legacy_forums/embedded/linux/f/354/t/590728

Also I suggest searching the Internet, there are many types of problems and associated solutions such as this one:

https://e2e.ti.com/support/legacy_forums/embedded/linux/f/354/t/564201

Can you please do some in-depth experiments on your end and then report back here what you find and/or how you were able to resolve the issue, if successful.

hello Andreas Dannenberg

thank you so much for your reply

after adding uEnv.txt file in sd card boot section kernel load successfully.

Fullscreen 1033.uEnv.txt Download

bootargs=console=ttyO0,115200n8 root=/dev/mmcblk0p2 rootfstype=ext3 rw rootwait ip=off lpj=3590144
bootcmd=mmc rescan; ext4load mmc 0:2 ${loadaddr} /boot/zImage; bootz ${loadaddr} - ${fdtaddr}
loadfdt=ext4load mmc 0:2 ${fdtaddr} /boot/am335x-evmsk.dtb
uenvcmd=boot

but still getting one small issue with this file, at first time power on kernel not booting after board reset kernel load and working fine....

should i create new thread for this issue...?

Are you saying after power up, the boot works all the way to "Loading Kernel..." only (and then gets stuck, like you reported initially), but after you issue a reset the boot will go all the way to Linux prompt?

If so, can you share a log of a full successful boot?

Have you run "memtester" at the Linux prompt (if not, please do that)?

Regards, Andreas

Also from the log it seems like your board does not use RTC, and it has not gotten disabled properly. Can you check the steps here: https://e2e.ti.com/support/processors/f/791/t/485319 to see if this cleans up your Kernel log. RTC mis-configuration is known to cause boot issues / hangs. This may not be responsible for the issue you reported, but at least it should help cleaning up your boot log. If so you would also want to disable the initialization of the 32-kHz oscillator in U-Boot by turning off CONFIG_SPL_AM33XX_ENABLE_RTC32K_OSC

a0797059@jiji:~/git/u-boot (ti-u-boot-2019.01-next-dev)
$ git grep -A 5 SPL_AM33XX_ENABLE_RTC32K_OSC common/spl/Kconfig
common/spl/Kconfig:config SPL_AM33XX_ENABLE_RTC32K_OSC
common/spl/Kconfig-     bool "Enable the RTC32K OSC on AM33xx based platforms"
common/spl/Kconfig-     default y if AM33XX
common/spl/Kconfig-     help
common/spl/Kconfig-       Enable access to the AM33xx RTC and select the external 32kHz clock
common/spl/Kconfig-       source.

Have you gotten a chance to run 'memtester' in Linux, stress-testing as much of the DDR as possible?

Regards, Andreas
